About this 0.5ct natural marquise diamond

This 0.5ct natural marquise sits in the half to three-quarter carat band, graded I colour (near-colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2566502812. Listed at 6 retailers as of November 1, 2026, with prices from HK$4,017 to HK$6,615, a HK$2,598 spread on the same certified stone. Yorxs lists it at HK$6,615. Cut grade matters more than carat or clarity for visible brilliance. If you can shift budget toward an Excellent or Ideal cut, do it before chasing higher colour or clarity.
